UNETE STAT CHARLES E. LINNIG, or 133311,. ILLINQ sQ To all whom it may concern."

' Be it known that I, CHARLES, Ei-LiNNIG, a citizen of the United States, residing in the city of Peru,'county of La Salle,and- State of'Illinois, have invented certain newand useful Improvements in Engravers" Clamps, of Which the following is a speci-- fication.

My invention relates to improvements in engravefis clamp and has for its object the production of an engravers clamp having a series of correlating removable and interchangeable jaws and in which the clamping mechanism can be so adjusted to allow a very extended angular movement, both sidewi'se as well as vertically, so that all manner of work may be successfully held in a substantialhianner while the work is done on the part located in the jaws. I

These objects, together with other objects readily apparent to thosefskilled in the art, I attain by the construction illustrated in the accompanying drawings, in which- Fig. 1 is a top view of my clamp,

Similar numerals represent similar parts throughout the severalviews. l' represents the base of my clamp, which has-a "screw 2 that has the shoulders shown, which screw is journaled in bearings 3 and 4 fastened'to 1. Screw 2 has a knurledheadfi by means of which it is rotated with the fingers. The shoulders shown on'screw'2 prevehtit-froni moving endwise; Mounted on screw 2 is "a nut 6 having a projection 7 "(see 5) which engages withthe movable or rear'par't 8 of my clamp.-= Part 8 has two conicalapertures 9 and 10 (see Fig. 1) throngh which pass the rods l1and12, which are'ffastened to and project from the stationary part 13 of my clamp, which part "13 is fastened to or projects from part 1 'asshown'. 1 Attached to but adjustably connected with movable part 8 in the manner shown (s efFig'sfa and 8) is a screw 14 which passes'through an aperture 1,3

nut 15 and' a washer 22, by means of which the movable part 8 is moved to and from engages'the lower part of 8 forms a stop for said part 8, said stop being located at the base of 8, so that when the wing nut 15 drawsgthepart 8 forward, said part 8 will tip so that the upper of part 8, or part16, will be closer to the upper part of 13, or part 17 thus giving, the jaw parts 18 and 19, which register in 17 and 16, a very powerful gripping action. Parts 16 andl? in my clamp are parts fastened to parts 8 and 13 respectively and so formed as shown (see Figs. 1., 2 and 5) that they have a socket part 20 and part 21 projecting into said socket, the two parts together forming a registering means whereby a large number of different shaped jaws, parts 18 and 19, can be interchangeably employed to hold the various complicated parts necessary to be held in the engravers art. Part 13 has two screws 23 and 24: spaced close to its outer ends which register on plates 25 in 8, by

- means of which the movable part 8 can be positioned so that it will be at angle to the part 13 instead of parallel with it, which enables my clamp to hold angular articles. In order that my system of jaw-pieces can be I use the registering piece shown in Figs. 10, 11 and 12, whose upper or holding part is the same as that above described except that it has a bottom plate 26 fastened to a plate 27, by means of projecting pins 28 and 29, which pins register with holes in the universal headof said clamps. It is evident from the above described registering piece that my system of jaws can be adapted for use with the clamps now in use. One of the jaw pieces used for such articles as spoon handles, etc, is shown in Figs. 13, 14k and 15, in which 30 is the base of the jaw-piece having the registering and locating slot 31' which register I .with the parts 20 and 21 of my clamp, as

above described, and a part 32 of a suitable soft ,materia l fastened to the base 30 and having the suitably shaped cavity shown. One of the jaw-pieces used for holding such articles as buttons etc. is shown in Figs. 16, :17 and 18 and 27 and 28 comprises the usual base 30 and registering slots 31 and shaped as. shown, having a soft metal part 35 vfastened to same on a plate 36, as shown. Beneath plate 36 is another part. 37 which has a. shouldered part 38 raised from same, which has the threaded aperture shown for screw 39. Journaled on shouldered part 38 is a gear wheel &0, which meshes with a gear wheel ll, whichis fastened to ashouldered cylindrical nut part 4L2, which is journaled in an aperture in part 37. Shouldered cylindricalpart 42 has the threaded aperture shown, into which fits the threaded rod 43,

which passes through an aperture in plate 36 and is fastened to a smaller suitably shaped and guided piece H, which is raised and lowered by means of the threaded rod 13 whenever the gear 40 is suitably rotated when pressed with the fingers, since when 4:0 is rotated, it being in mesh with 41, which turns the nut 42, which raises or lowers the piece la, which is so guided as shown that it cannot rotateJ By these means, above described, the work can-be suitably positioned to properly hold it in the metal parts 35. The soft metal part 35 is so shaped that a set ofsecondary jaw parts, shown in Figs 21, 22, 23 and 24 and 25 and 26 can be inserted to handle different shaped articles. My

universal hole head jaw-piece complete is shown in Figs. 29, 30 and 31 and is of the shape shown, each part having the usual base 30 and registering slots 31 and has a plurality of holes 33 in the top of same. Another one of the jaw-pieces is shown in Figs. 32, 33 and 34 and is similar to that shown in Figs. 13, M and 15 except that it is formed entirely of wood or soft metal (it having no part 32 of different material) and that it has two holes 3 1, by means: of which it can be used with my universal hole head jaw-piece or with similar parts of clamps now in use. The turntable or fixture I use for; mounting my clamp on is shown in Figs. 35 and 36 and which comprises a partial ball 35 shaped as shown, having a part 36 rotatably mounted on same by means of pin 37. Part 36 has slidably mounted in it a part'38 to which the base of my clamp is fastened by means of the screws shown at 39. Part 38'is moved by means. of the shoulderedscrew 40, which is suitably mounted in the part 36 by means of the plates 41. The turntable is held in various positions by means of the so -calledv leather doughnut 4L2, indicated in dotted lines in Fig. 35 and which rests on the work bench.

In use my clamp is operated as follows-- The proper jaw-pieces for such an article as a button are selected and these jaws registered into the corresponding part of the clamp and the toe-piece on the lower adjusting screw is set so as to give the jawpieces the required amount of angle or tilt and theclamp is then'nearly closed on the button. The button then is raised or, adjusted to the proper position by means of the adjusting screws on thebutton holding jaws as above described and then the thumb or' 1O form shown, but desire to'have it taken in changeable jaws to handle all manner of I l .jCtl'Oni fIOIIISfild. base having suitable regwork and in which the clamping mechanism can be adjusted to allow -a very extended angular movement, both sidewise as well as vertically and I haveac compl'ished same in a very simple aird i inexpensive manner. j 1
